WINDOW OR DOOR SCREEN.

Specification of Letters Patent.

Patented Dec. 23, 1919.

Application filed October 15. 1919. Serial No. 330,696.

To all whom it may concern:

Be it known that I, WILLIAM J. SMITH, a citizen ofthe United States, residing at Roswell, in the county of Chaves an'd State of New Mexico, have invented certain new and useful Improvements in Window or Door Screens, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to the art of window and door screens, and more especially to an improved device for attaching wire screen or wire fabric to window or door frames.

Asa primary object of the invention, it is the aim to provide a simple and improved contractible frame, which is simple, efficient and practical in construction, and is adapted for attaching wire screen or fabricto window or door frames without nails or like securing means.

A further object of the invention consists in the provision of'a contractible screen attaching frame, the side, end and intermediate pieces of which consisting of collapsible sections, and improved joints, whereby the sections may be collapsed inwardly, so that the screen attaching frame may be contracted, so as to fit within the window or door frame, and to engage the groove of said frame, whereby the wire screen or fabric may be attached, and which screen or fabric is attached to the contractible frame, by wrapping or folding the fabric or screen about the side and end pieces thereof, prior to forcing the contractible frame in the groove.

V A still further object of the invention is the provision or formation of recesses on the 'top and bottom or end pieces of the wooden frame, to permit of the engagement of the thumb and finger of the hand engaging the contractible. metal frame, so as to facilitate in breaking the joints of the contractible frame.

WVhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what. is claimed.

["The invention comprises further features and combination of parts, as will be hereinafterset-forth, shown in the drawings and claimed.

In the drawings:

Figure 1' is a view in perspective of a window screen, showing the wooden frame,

and illustrating the screen or wire fabric as fastened in the groove of such frame by means of a contractible metallic frame.

Fig. 2 is an enlarged detail perspective view of one corner of the wooden frame, showing a portion of one corner of the metallic frame in the groove of the wooden frame, and the screen' or wire fabric fastened in place.

Fig. 3- is an enlarged plan View of the contractible metallic screen attaching frame showing the various sections of the side, end and intermediate pieces. extended in full lines.

Fig. 4 is a view similar to Fig. 3 showing the metallic frame contracted.

Referringmore especially to the drawings, 1 designates a wooden frame, which comprises the sideand end pieces 2 and 3. The inner edges of the side and end pieces of the wooden frame are. provided; with elongated grooves l and 5. The side and end pieces of the wooden frame may be secured together at the corners in any suitable manner (not shown).

A metallic frame 6 is employed for attaching-the wire screen or fabric 7 to the wooden frame, without nails or other like securing means. This metallic frame comprises the side and end pieces 8 and 9 and the intermediate piece 10. The side pieces of the metallic securing frame comprises a plurality of sections 11, 12, 13 and 14C, or as many sections as may be required to fit the wooden frame. Certain of the ends of the sections 11 and lt are provided with bifurcations 15, in which the reduced extensions 17 of the adjoining ends of the sections are pivotallyconnected by the pivot pins 18. Certain of the reduced extensions of the sections are beveled off on their corners, so as to permit the sections to pivotally move relatively to each other. This is facilitated by beveling off the shoulders 19, as shown at 20. The bevels of the corners of the reduced extension, and the bevels 20 of the shoulders, are formed relatively to each other, in other words alternately arranged, so that the sections may inwardly collapse, whereby the metallic frame may be contracted.

The ends of the-side pieces at the top and bottom of the metallic frame have bifurcations 21, which receive the reduced extensions 22 of the side ends of the end pieces. The shoulders 23 adjacent the extensions 22 have bevels 2%, which act to permit the end pieces and side pieces to pivotally move relatively to each other, so that the metallic frame may further contract. The crotches of the bifurcations 21 have bevels 25, which also permit the side and end pieces to contract.

The end pieces each comprises sections 26 and 27 The inner ends of the sections 27 have bifurcations 28, in which the reduced extension 29 of the sections 26 are pivotally mounted as at 30. he shoulders 31 adjacent the reduced extensions 29 have bevels 32. The crotches of the bifurcations 28 have bevels 33, which cooperate with the bevels 32, to permit the sections 26 and 27 to collapse inwardly.

The intermediate brace piece comprises two sections 34 and 35. The section 34: has a reduced extension 36, which is pivotally mounted in the bifurcation 37 of the section 35, as indicated'at 38. The crotch of the bifurcation 37 has a bevel 39. The shoulders 40 of the reduced extension of the section 3 1 is provided with bevels 41. The bevels 39 and 4-1 cooperate to permit the intermediate brace piece 10 to collapse, for. contracting the metallic securing frame.

The section 8 of the side pieces have slots 42, in which the extensions 441 of the outer ends of the sections 34L and 35 of the intermediate piece 10 are pivotally mounted as at 41-5. The shoulders adjacent the extensions 4% have bevels 46, which cooperate with the bevels 17, which are formed at certain of the ends of the slots 42. The opposite ends of the slots 42 have bevels 18, which permit the extensions of the outer end of the sections 34: and35 to move when the sections are collapsed.

In attaching the wire screen fabric to the wooden frame the marginal edge portion is wrapped around the side and end pieces of the metallic securing frame, while the metallic frame is in a contracted or collapsed condition. The metallic securing frame is then expanded so that the wire screen or fabric may be engaged by the lugs 49. After attaching the screen in this manner, the metallic securing frame is placed within the wooden frame, and the side and end pieces are then distended, allowing the side and end pieces to engage the grooves 5 of the side and end pieces of the-wooden frame, thereby clamping the screen or wire fabric securely in place. It is obvious that when the screen is so attached, it will be drawn tight, owing to the extensibility of the metallic securing frame.

The invention having been set forth, what is claimed as new and useful is:

1. In a window screen, the combination with a wooden frame having a groove in the inner marginal edges thereof, of a metallic securing frame comprising sectional side and end pieces adapted to be extended or contracted, to engage and disengage the groove of the wooden frame, and a piece of wire screen clamped in the groove by the metallic securing frame.

2. In a window screen, the combination with a wooden frame having groove in the inner marginal edges thereof and a piece of wire screen or fabric adapted to engage said groove, of an extensible and contractible metallic securing frame to hold the wire screen in engagement with the groove to hold the same stretched.

3. In a window screen, the combination with a wooden frame having a groove in the inner marginal edges and a piece of wire screen adapted to engage said groove, of an extensible and contractible metallic securing frame to hold the wire screen or fabric in engagement with the groove to hold the same stretched, said extensible and contractible securing frame comprising side and end pieces, the side and end pieces comprising a plurality of sections pivotally united, and having cooperating beveled parts, to permit the sections to collapse, whereby the securing frame may be contracted or extended.

4. In a window screen, thecombination with a wooden frame having a groove in the inner marginal edges and a piece of wire screen or fabric adapted to engage said groove, of an extensible and contractible metallic securing frame to hold the wire screen in engagement with the groove to hold the same stretched, said extensible and contractible securing frame comprising side and end pieces, the side andend pieces comprising a plurality of sections pivotally united, and having cooperating beveled parts, to permit the sections to collapse, whereby the securing frame may be contracted or extended, and an intermediate brace connecting the side pieces, said intermediate brace comprising collapsible sec tions, the outer ends of the colla isible sections of the brace being pivotally connected to the side pieces of the securing frame.

In testimony whereof Ihere'unto affix my signature.

WILLIAM J SMITH.
